IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 122,645, dated January 1872.

Specification describing a certain Improvement in Spring Bed-Bottoms, invented by BEN- JAMIN H. OTIS, of Havana, in the county of Mason and State of Illinois.

Figure 1 is a vertical longitudinal section of a bedstead to which my improvement hasbeen applied, taken through the line ,00 m, Fig. 2. Fig. 2 is a vertical cross-section of the same taken through the line y y, Fig. 1. Fig. 3 is a detail perspective view of the end part of one of the longitudinal slats.

Similar letters of reference indicate corresponding parts. I

My invention has for its object to furnish an improved spring bed-bottom, simple in construction, effective and reliable in use, and not liable to get out of order; and it consists in the construction and combination of the various parts of the spring bed-bottom, as hereinafter more fully described.

A represents the posts, B the side rails or boards, and (J the end rails or boards of the bedstead, aboutthe construction of which parts there is nothing new. D are the longitudinal slats upon which the bedding rests. The ends of the slats D rest upon cross-bars E, and are slotted to receive the pins F attached to said cross-bars at suitable distances apart to keep the said slats in their proper relative positions while allowing them to yield to the pressure of the weight resting upon them. Around the middle parts of the cross-bars E are placed square rings or loops G, into the lower parts of which are inserted the inner ends of two springs, H. The ends of the springs H are grooved transversely upon both sides to prevent them from slipping out of the loops G,

and so that the said springs may be turned over should they become permanently bent or set. I are blocks, which are attached to the under sides of the cross-bars E, to serve as fulcrums for the lever-springs H. The fulcrum blocks I should be notched or flanged to prevent the springs H from slipping from them. The outer ends of the springs H rest in sockets or upon cleats J formed in or attached to the side boards B of the bedstead. If desired, the position of the cross-bars E, loops G, fulcrum-blocks I, and lever-springs H, may be reversed or inverted. In this case a second cross-bar should be placed upon the outer and upper ends of the springs H, to receive and support the ends of the longitudinal slats D, the pins F being attached to the said second cross-bar.

I do not claim supporting a bed-bottom by Witnesses S. FRANKINFIELD,
